  • Abstract
    The optical characteristics of a metal/p-Pb1-xSnxTe/p+ -Pb1-xSnxTe three layers waveguide were studied. The effective index, propagation losses and electric field distribution of the TE-modes were calculated numerically. Approximate expressions for the losses derived by first-order perturbation methods were found to agree with the exact solutions. The conditions for transversal and lateral single-mode operation of the waveguide were discussed. The coupling constant of a metal/Pb1-x SnxTe DFB waveguide produced by periodic variation in the active layer thickness and on-off metal contact modulation was calculated by the perturbation technique
